Nakahori Mina

She is 25 years old. She is the wife of the main character's uncle (apartment owner).

She is a kind and cheerful woman, but she also has a cute side, sometimes being jealous of the main character.

She is widowed at a young age, but continues to manage the apartment. She lives in the room next to the main character's and sometimes you can hear her lewd voice in the middle of the night...?
